I accidentally went past the collectible for the extra dash, and now I can't go back to get it. It was very challenging but fun though!

Got all berries (including title berry) in roughly 12 minutes.

This mod is honestly not that hard as it claimed to be (although this is coming from a guy who've speedran and made celeste classic mods before).

I like the challenge (although post chest levels are mostly the same level with almost no changes with actual value)

I could try gem skip later :P
